Advisory

Source description from Wordfence Intelligence, credited to TaiYou.

The LiteSpeed Cache plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 6.5.1. This is due to the is_role_simulation() function not properly providing protection against unauthorized use of the function. This makes it possible for unauthenticated attackers to simulate roles such as administrators which provides elevated access to the site. Please note there are a lot of pre-requisites for this to be exploitable.
